Question

Solve by elimination 5x-y=12 3x+2y=2

Answer 1

(2)5x-y=12
   3x+2y=2
10x-2y=12
 3x+2y=2
13x=2
x=0.15

Answer 2

Eliminate y
time first equation by 2 an add them together


10x-2y=24
3x+2y=2 +
13x+0y=26

13x=26
divide both sides by 13
x=2

sub back

3x+2y=2
3(2)+2y=2
6+2y=2
minus 6
2y=-4
divide 2
y=-2

(x,y)
(2,-2)
